Is it ever reasonable to date a woman just so she can have kids?

I know her for quite a while now, and she waited until my graduation to tell me that she wanted to have kids some day. I've asked her before, but she said she preferred her job life. And now that I saw her fail one relationship after the other because she hardly gets to know these guys, I'd think "a stable man could not only support her but also raise kids with her".

Now it was her who gave up on me after I took almost 4 years for graduating and finding a career. I've seen parents with disabled kids, because either the mother or the father was in their late 30s. And because it's not her fault, I'd think about advising her into having kids rather now than later. In addition, I wonder how many men she talked to about having kids if she told me when we knew each other for over 3 years already.

Aside from a stable job, would it be a wise decision to offer fatherhood to her kids because there's likely noone else willing?
